MTS ANNOUNCES UPSIZE AND PRICING OF PUBLIC OFFERING OF COMMON STOCK AND PRICING OF PUBLIC OFFERING OF TANGIBLE EQUITY UNITS

Eden Prairie, Minn. – June 9, 2016 –MTS Systems Corporation (NASDAQ: MTSC), a leading global supplier of high-performance test systems and position sensors, announced today that it priced an upsized offering of 1,650,000 shares of Common Stock at $42.00 per share. The Common Stock offering was upsized from an originally announced 1,500,000 share offering. The Company also priced a previously announced offering of 1,000,000 8.75% tangible equity units, each tangible equity unit with a stated amount of $100, resulting in aggregate gross proceeds of $100 million. The Company has granted the underwriters of the Common Stock a 30-day option to purchase up to an additional 247,500 shares of Common Stock and the underwriters of the tangible equity units offering an option to purchase, within a 13-day period beginning on, and including, the issuance date for the tangible equity units, up to an additional 150,000 tangible equity units. The completion of the Common Stock offering is not contingent on the completion of the tangible equity units offering, and the completion of the tangible equity units offering is not contingent on the completion of the Common Stock offering, and neither offering is contingent on the completion of the PCB Group, Inc. (“PCB”) acquisition.

Each tangible equity unit will consist of a prepaid stock purchase contract and an amortizing note. Unless earlier settled or redeemed, each stock purchase contract will automatically settle on July 1, 2019 (subject to postponement in limited circumstances) for between 1.9841 and 2.3810 shares of the Common Stock, subject to certain adjustments under the terms of the agreement governing the purchase contracts. The amortizing notes will pay equal quarterly installments of $2.1875 per note (except the first such installment, which will be $2.5764 per note), which will constitute a payment of interest and a partial repayment of principal, and which in the aggregate will be equivalent to a 8.75% cash payment per year with respect to each $100 stated amount of each tangible equity unit. The amortizing notes will have a final installment payment date of July 1, 2019 and will be unsecured senior obligations of the Company.

In connection with the pricing of the tangible equity units, the Company has entered into capped call transactions with an affiliate of J.P. Morgan Securities LLC and an affiliate of Wells Fargo Securities, LLC (the “option counterparties”). The capped call transactions are expected to reduce potential dilution to the Company’s Common Stock upon any settlement of the purchase contracts, with such reduction subject to a cap. The strike price of the capped call transactions will initially be $50.40 per share of the Common Stock, representing a premium of approximately 20.0% above the public offering price of the Common Stock in the Common Stock offering, and is subject to certain adjustments under the terms of the capped call transaction documentation. The cap price of the capped call transactions will initially be $58.80 per share of our Common Stock, representing a premium of approximately 40.0% above the public offering price of the Common Stock in the Common Stock offering, and is subject to certain adjustments under the terms of the capped call transaction documentation.

In connection with establishing their initial hedge positions with respect to the capped call transactions, we expect that the option counterparties (and/or their respective affiliates) will enter into various derivative transactions with respect to the Company’s Common Stock concurrently with or shortly after the pricing of the tangible equity units and the option counterparties (and/or their respective affiliates) may unwind these various derivative transactions and purchase shares of the Company’s Common Stock in open market transactions shortly following the pricing of the tangible equity units. These activities could have the effect of increasing, or reducing the size of a decline in, the market price of the Company’s Common Stock or the trading price of the purchase contracts or tangible equity units concurrently with, or shortly following, the pricing of the tangible equity units.

The Company expects the net proceeds of the Common Stock offering to be $65.1 million (or $74.9 million if the underwriters exercise their option to purchase additional shares in full), and the net proceeds of the tangible equity units offering to be $97 million (or $111.6 million if the underwriters exercise their option to purchase additional tangible equity units in full), in each case after deducting underwriting discounts and commissions.

The Company intends to use approximately $6.9 million of the net proceeds of the tangible equity units to fund the cost of the capped call transactions and the remaining net proceeds of the offerings to partially fund the acquisition of PCB. If the acquisition of PCB is not completed, the Company intends to use the net proceeds from these offerings for general corporate purposes, including strategic investments and acquisitions. If the tangible equity units offering is completed but the acquisition of PCB is not consummated, the Company may redeem all, but not less than all, of the outstanding purchase contracts by issuing a redemption notice. The Company will pay a redemption price at that time in cash or in shares of Common Stock in accordance with the terms of the purchase contracts. If the Company elects to redeem the purchase contracts, it may be required by the holders thereof to repurchase the amortizing notes at the repurchase price set forth in the amortizing notes.

J.P. Morgan Securities LLC and Wells Fargo Securities, LLC are serving as the joint book-running managers for the Common Stock offering and for the tangible equity units offering. The shares of Common Stock and tangible equity units, including the component stock purchase contracts and amortizing notes, have been issued pursuant to an effective registration statement previously filed with the Securities and Exchange Commission (the “SEC”) on Form S-3 and are available for review on the SEC’s website at www.sec.gov.
